Class Diagrams

[SurfingNerd]

The archtiecture is really hard to understand without any additional resources.
after crawling the web, asking other development, we just came to the conclusio that there are no resources available.

But fixing current instabilities requires a better understanding.
A autogenerated class diagram would also be a good help.

FIrst attempt to create such failed.
Tool used: https://github.com/adjivas/ml
seems to be connected with an error in the abbonded library syntex_syntax.
This might get fixed: adjivas/ml#7
This compile error is also targeted here: rust-lang/rust#68729
